But just because one of them has a black jacket and the other one has a brown jacket, that doesn't mean they're supposed to resemble Claude.

Funny you mention that though, I remember when I was real young, I would watch the first cutscene of GTA 3 and then play Vice City. I hadn't gotten to the part in III where you actually meet the Cartel other than that Bomb da Base mission, which I couldn't beat for some reason. But yeah, I saw the cartel dude running out of the bank with Catalina and Claude in the first cutscene and the first thing I thought after playing Vice City - that old f*cker is Tommy.
